You could also check East Coast Gear Supply. They happen to be local to me so I bought from them AND had them do the installation work since gear patterning isn't a skill I possess. I'm running Nitro gears based on the recommendation from ECGS. When I mentioned Yukon gears they had some not-so-good things to say about them.

As these guys do gear work regularly AND they warrant their work for 5 years, I believe they made their recommendation and comments based on solid experience. They were willing to put in any gears I wanted, by the way. (i.e. They pushed nothing on/at me and merely recommended a manufacturer based on my diff and the ratio I wanted.)

I dealt with Chase when there. I originally thought he was just a knowlegdeable sales person but it turned out he's the owner. It was refreshing to see an owner present in his shop. He drives a lifted Cherokee that rolls on 37's -- some insane work to push those puppies, so he's an enthusiast, too.
